Parse state files into a temporary host so malformed input fails cleanly instead of aborting, and commit parsed data atomically. Start the temporary host from the caller's tx_context so a state file without tx_context (or with missing fields) keeps the values the caller already established; fields present in the JSON are overlaid on top. Treat explicitly loaded empty accounts as empty for EIP-161 instead of inferring non-emptiness from a non-zero code hash. Pre-warm the Cancun KZG point evaluation precompile (0x0a) per EIP-4844, keeping the precompile range revision-aware. Keep the JIT cached memory base/size in sync after no-expand KECCAK helpers, including the specialized two-word, caller-slot, and calldata-slot macro-op paths, so direct memory operations that follow never read a stale base pointer. Add regression tests for issues DTVMStack#592, DTVMStack#593, DTVMStack#594, DTVMStack#601, DTVMStack#602, DTVMStack#603, DTVMStack#606, and DTVMStack#610, plus tx_context preservation/overlay and KECCAK macro-op coverage in both interpreter and multipass JIT modes. fix DTVMStack#591, DTVMStack#592, DTVMStack#593, DTVMStack#594, DTVMStack#595, DTVMStack#601, DTVMStack#602, DTVMStack#603, DTVMStack#606 Co-authored-by: DTCoder <noreply@dtcoder.local>

Replay the EIP-2930 access list on the caller's host after the atomic loadState commit. Account warmth lives in the host access journal, so warming the temporary parsing host discarded access-list entries and execution charged cold-access gas for warm accounts. Malformed entries are validated into a temporary list during parsing and applied only after the parsed state is committed. Keep the cached memory base pointer/size in sync after the CODECOPY and CALLDATACOPY no-expand helpers as well. The no-expand helpers run on a proven range, but the instance memory backing buffer may still be materialized or rebased on first use, so direct memory operations that follow must not read a stale base pointer or size. This makes the reload-after-helper contract uniform across all no-expand helper call sites whose execution continues (RETURN/REVERT end the frame and are excluded). Add regression test AccessListPrewarmSurvivesLoadState covering account warmth, storage-key warmth, and malformed-entry tolerance in loadState. Co-authored-by: DTCoder <noreply@dtcoder.local>
The revision-aware EIP-2929 prewarm range stopped at Cancun KZG point evaluation precompile (0x0a), so on Prague the BLS12-381 precompiles at 0x0b-0x10 stayed cold and the first CALL/STATICCALL to such a precompile charged cold-access gas at transaction start. Extend the warm precompile range to 0x10 for EVMC_PRAGUE per EIP-2537 and keep 0x11 and above cold. Cover the Prague range, the pre-Prague boundary, and the 0x11 boundary with regression tests.

Pre-warm exactly the Prague BLS precompile range through 0x11 and retain pre-Spurious Dragon existence semantics for previously-created empty accounts.

Select the host revision on the CLI path so pre-Spurious Dragon empty-account semantics apply. Maintain transaction warmth with an unbounded access set instead of the capped access journal, and reject non-object account entries before RapidJSON member access.
